Value Collection C702080 Hex Head Cap Screw 5/16-18 Grade 5

Product Description

The Value Collection C702080 is a 5/16-18 hex head cap screw measuring 3-3/4 inches in length under the head. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener is partially threaded and dimensioned to the ASME B18.2.1 standard with thread strength conforming to SAE J429. The unified coarse (UNC) thread form provides reliable clamping force in general mechanical assemblies. It is a standard trade fastener used by HVAC technicians, electricians, plumbers, and general contractors when fastening structural or mechanical components that require controlled thread engagement with a mating nut or tapped hole.

This screw is suited for light-to-medium duty industrial and mechanical applications where inch-standard fasteners are specified. The partial thread design allows the unthreaded shank to act as a shoulder in clearance holes, which is common in fabrication, equipment mounting, and panel assembly work. Sold in a package quantity of 25, this SKU is appropriate for both shop stock and job-site use.

Key Features

• Grade 5 steel construction meets SAE J429 minimum tensile strength requirements for medium-strength fasteners
• Zinc-plated finish provides corrosion resistance suitable for indoor and light-duty exposed installations
• Partially threaded shank allows use in clearance-hole and shoulder-bearing applications
• UNC 5/16-18 thread form is compatible with standard inch-series nuts and tapped components
• Conforms to ASME B18.2.1 hex head cap screw dimensional standard
• Sold in a 25-piece package for efficient job-site or shop restocking

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use with 5/16-18 nuts, threaded inserts, or tapped holes in steel, aluminum, and similar substrates.

Installation Notes

Installation is performed using a standard hex wrench or socket driver sized for a 5/16-18 hex head cap screw. Ensure mating threads are clean and free of debris before assembly. Apply thread-locking compound or hardened washers where vibration is a concern and where the assembly specification requires it. Follow applicable mechanical, structural, or equipment manufacturer guidelines for fastener torque requirements.
